‘Physicalism: is it all transference?’ considers what causation is rather than what our concept of cause is. It begins with physical transference theories – the physical transfer of energy from one place to another. The concept of reciprocity is discussed where causation does not just change the effect: there is also an equal and opposite change to the cause. Understanding causation as a physical process could allow us to solve the well-known problem of common causes, but it becomes problematic when considering non-physical subjects such as economics and psychology. Reductionism and emergentism are also explained; when considered as something that also occurs between wholes, causation becomes a bit more manageable.
